Interactive Brokers calculates an internal funding rate based on a combination of internationally recognized benchmarks on overnight deposits ex: Fed funds, LIBOR and real time market rates as traded, measured, in the interbank short-term currency swap markets, the world's largest and most liquid market. IB's interest model starts with the fixing rates and incorporates the dynamic market pricing to produce a midpoint or "Benchmark".
Around this benchmark, IB adds a spread to determine deposit and borrowing rates applicable to client balances in each currency. Spreads are tiered such that larger balances receive more favorable interest treatment by virtue of smaller spreads to the benchmark.
IB's benchmark for each currency is the reference rate around which our credit, debit, stock-loan, and other interest rate linked calculations are determined. IB uses a combination of internationally recognized interest rate fixings such as LIBOR, Fed Funds, etc and dynamic interbank rates determined from foreign exchange and money-markets to calculate an IB Reference Benchmark rate.

We pay interest to clients for credit balances, based upon rates available in the interbank deposit market. For those clients that hold large cash balances in multiple currencies, we offer the ability to take advantage of the Forex Swaps market to potentially earn higher rates. This program is not designed for and would not benefit any client who holds a single-currency long balance. The mechanics behind this program involve the buying of a currency for settlement one day out and the selling of the same currency two days out, the difference in value between the two settlement dates being the interest earned.
We automatically keep rolling the swaps until you no longer meet the minimum balance criteria, or you instruct us to halt the program.
